T0 all `whom t may concern:

Be it known that '1, ALBERT T. 'HinAMAN, a citizen of the United States, residing at Newark, in the county of New Castle and State of Delaware, have invented certain new and -useful Improvements in Stock Regulators; land I do declare the following to be a full,- clear, `andexact description of the invention, such as will enable others 'skilled iii the'art to which it appertains to kmake and use the saine.

This invention relates to an improved stock regulator for use 4in connection with paper machines 'andy one vobj ectA of the inveiition is to fprovid'e the stock regulator with improved means Vforcontrolling feeding of lthe `stock and to'furtlier provide improved -iiiea'nsfor preventing'splashing ofthe pulp against the sides ofthe spoutle'ading to the 'pulp bucket fand also prevent splashing of Ithe pulp against the sides of the upper portion of the "pulp bucket.

n Anotherobject of the invention is to provide improved. means for controlling upward and downward movement of the pulp bucket and'to vprovidean improvedtype of 'gate for controlling passage of the pulp throughfthegate leading from the pulp box into the spout vleading to the pulp bucket, this 'gate 'being adjustably connected with across bail carried by arms from' which the pulpbucket is suspended.

Another object of the invention is to pro- 'vide an improved arrangenient of parts for 'controlling rotation of la'fshaft carrying the arms from which the pulp bucket is suspen'ded softhat the pulp-bucket may be normally retained at a desired point but per- `niitted Iof vertical movement either upwardly or 'downwardly 'as the amount of 'pulp' in the bueketvaries.

Another object of the invention is to provide an improved `gate for'controlling'pas- A`sage of the pulp.

Another' object ofthe invention is toprovvidea stock -regiilator'wh-ich will be very feieient. in operation and simple inconstructien.

` This invention is illustrated' in thefiac-'coin- "panying drawings, "wherein: Y

`Figure l is a transverse sectional view taken along the line 4-4 of Fig. 1.

This improved-stock regulator is provided 'f with a pulp box l having therein an auxiliary chamber 2 provided with an inlet opening 3 and having communication with the interior of the pulp box 1 through an opening controlled by a gate 4. rPhe pulp in the fpulp box 1 is to pass out ythrough ak passage in the front wall of the "pulp box and through a discharge pipe 5. This discharge pipe 5 is rectangular in cross section and adjacent its free end has itsbottom wall eut short to provide a discharge passage 6 through which the pulp may pass into the depending -spout 7 'which is secured to the free end portion of this pipe 5. This pipe 5 is provided in its upper wall with a ,passage 8 through whicheXtends a gate 9 yand within the pipe 5 :against the side walls thereof, there has been provided guide strips 10 'so that movement of the gate 9 will be controlled. The head 11 at the end of the pipe 5 is mounted for movement iiitofaiid out of a closing position by means of the rivets 12 and a handle 13 is provided sotliat this head 11 may beeasily swung into and out of .la closing position. An apron 14 which is called a splash apron is pivotally mounted atits upper end within the pipe 5 and' has its free rend portion yextending downwardly through the discharge passage '6 of this pipe. Therefore, as the pulpgpasses through'the pipe y'beneath tlieigate 9,:this

apron 14 willbe swung to ypermitr the pulp topass downwardlyfinto the spout 7 but will from striking against n the device. This spoutf'( is rectangular iiiv cross 'section and.preferably oblong andis provid- #ed l at--itslower end with a closure plate orl head 15, the walls of thespout ri'.being.pro-

vided with :discharge fopenings 16 adjacent "the hea`d=115=solthat the 'pulpwillf pass from tlii's,"sp'oiit` through theside openings 16. It is'd'esired toiprevent this pulp lfroni striking of lthe 'walls of the pulp bucket l17 where it Vmight adhere andgivethe bucket added weightfsand therefore there 'has been i provided a hood 18 1 which tsi uponzzthe 'repent 7 .and featured thereto by means of brackets 19. It will be readily seen that as the pulp passes through the discharge openings 16, it will strike the hood 18 and will drop directly :into the bucket 17 upon the mass of pulp already in the bucket.

This bucket is to be suspended so that it may have vertical movement in case the quantity of pulp in the bucket should vary and the gate 9 is to be connected with the structure for mounting the bucket so that as the bucket moves vertically, the gate 9 may be moved towards an open or a closed position. The gate moves to an open position when the quantity of pulp is reduced beyond the normal amount so that more pulp can pass into the bucket than under normal conditions and the gate is to move towards a closing position so as to reduce the quantity of pulp passing through the spout 7 in case the bucket contains more than the normal amount of pulp. This bucket 17 is provided with hanger bars 20 which are secured to the bucket 17 adjacent its upper end and extend upwardly and are provided at their upper ends with bearing eyes 21 which extend between the hinged ears 22 at the forward end of the lever arms 23 and are secured by pivot pins 24 at the ends of the cross bar 25 which extends between the forward ends of the lever arms. This cross bar which serves to pivotally connect the hanger arms 20 with the lever arms 23 is provided intermediate its length with a passage 26 through which extends the threaded stem 27. This stem 27 is loosely connected with the gate 9 as shown at 28 and carries nuts 29 for engaging the upper and lower faces of the cross bar 25 and securely but adj ustably holding the stem in a desired position with the gate 9 open the desired amount. It will thus be seen that the gate may be set at the proper point to permit a predetermined amount of pulp `to normally feed through the pipe 5 into the spout 7 and retain the pulp in the bucket 17 at the normal level. The lever arms 23 are carried by a shaft 30 which is journalled in bearings 31 carried by the pulp box 1 and these arms extend rearwardly over the pulp box and carry weights 32 which are adjustable upon the arms so that they can exert the desired amount of leverage. It has been found that the hanger means cannot be properly adj usted by means of the weights 32 alone and therefore there has been provided a handle bar 33 which carries an adjustable weight 34 and in addition to the handle bar, there has also been provided a mast formed by bars 35 which extend upwardly in converging relation from the shaft 30 and have their upper ends connected by a pin '36 which carries a block 37. This block 37 which is loose upon -the pin 36 carries a cable 38 which extends rearwardly and over the pulley wheel 39 carried by the support 40. A weight 41 is carried by this cable 38. lt will thus be seen that the bucket 17 will be normally retained in a desired position and that vertical movement of the bucket will be controlled by the weights 32, 34 and 41. The leverage exerted by the weight 41 cannot be changed but the leverage exerted by the weights 32 and 34 can be changed by adjusting these weights upon the arms 23 and ln order to control passage of the pulp out of the pulp bucket 17, there has been provided an outlet spout having an upper bucket engaging section 42 and a lower section 42 which are secured together by bolts 43. The upper section 42 is reduced to provide a seat 44 in which is slidably mounted a gate 45 which extends between the forward portions of the two sect-ions 42 and 42l and has its outer end portions provided with a depending fork portion 46 which engages an annular groove formed in the hub 47 of the adjusting wheel 48. This wheel 4S is mounted upon the threaded stem 49 which extends from the lower section 42 and it will be readily seen that when the wheel is rotated7 the gate may be moved towards an open position or touf'ards a closed position. A neck 5() is carried by the lower section of the collar formed by the two sections and extends downwardly into a pipe 51 through which the pulp will pass to the paper machine. The pulp can therefore pass freely into this pipe 51.

When in use, the pulp passes from the pulp box 1 through the pipe 5 and beneath the gate 9. After passing beneath the gate 9, the pulp moves the apron 14 to an open position and drops down through the spout 7 until it strikes the bottom or head 15 of this spout. The pulp then vpasses out through the discharge head 15 and down into the pulp bucket which will be filled to the normal capacity. This normal capacity in the present illustration is indicated at 52 but it will be understood that the normal capacity may vary. By turning the hand wheel 38, the gate 45 may be opened the desired amount so that the pulp may pass through the neck 50 and down into the pipe 51 through which it will pass to the paper forming machine. As the pulp flows out. of the bucket. it will be replenished by the pulp flowing spout 7. lf the pulp flows into the bucket at a slower rate of speed than it passes out through the gate, the amount of pulp in the bucket will decrease beyond the. normal amount and therefore the weight will be reduced. The weights 32,34 and 41 will then cause the bucket to move upwardly and as this bucket moves upwardly, the gate 9 will move upwardly to permit an additional amount of pulp to pass through the spout 7 into the same through the ,.I..

1 naaien 1 and increase the vamount of pulp inthe l bucket until it has reached the normal 'capacity. It will'thus'be'seen that the pulp will be kept at the normal level. Ofcourse, it

atpthe normal lrate tspeed and the pulp will be retained in thebucket atthe'normal i level and fed properly into vthe pipe.
